Cowl Air Cleaner

[KevinW]

Do the 70 AC versions have the notch in the snorkel? I have a GM AC and it has the more rounded snorkel without the notch. It has the 1" 90 U bent tube, not the double 45 degree repro. It also has a lot of forming wrinkles instead of the smooth repro, so I am sure it is GM. It could be an over the counter one, but I'm not sure. Any help? Anyone have a pic of an original foctory 70 version?

I believe the notches in the snorkle was what they were using throughout 69-72 production,and possibly available for a few years afterwards..It's possible there was more then one manufacturer of these and one had a slightly different design then the other.
Your's sounds like a later Gm designed licensed piece to me that is not exactly true in detail to the original design.

I should explain that when I say repop,to me that means a later on manufactured piece,(GM licensed or not),that has lost some of it's original details during translation,to the original part once used on the assembly line.
I understand if others don't classify them that way.

MR70, I hear what you are saying. The thing that has me stumped is the 1" vent tube (used in BB applications). All the repops I have seen have the 2 45 deg tube and are smoothly formed. As you can see in the pic, mine is not I bought this back in the early 80s before the repopers were running. And it was well used before I got it. It has the cut ring. I want to put this up on ebay soon and want to make sure I state the correct origins of this. Opinions welcome! Thanks

The guy I bought my original from, also had an NOS one with the ridge (still in the box, but I never checked for a date code. It had the radiused 90* elbow like the pic above. Can't speak to the notch, as I was not educated enough to know about it. (thanks to Rick, I learned a little more)

Here's an old discussion from Camaros.net ~with pictures~ just about ZL2 cowl air cleaners. http://www.camaros.net/forums/showthread.php?t=54696

Thanks John. Yes, I wrote that article quite a while ago and it was used in the Chevy punch magazine. This air cleaner is the 70 Chevelle one from that article. Since then I was educated about the notch in the snorkle. This air cleaner does not have the notch, but all other signs are correct for a factory GM air cleaner. I'm still trying to figure this one out. Thanks though!
